IMPRovEMENrm HAIRLCLIPPI'NG Devices.

The Schedule referred to in these Letters Patent and making part of thesame.

- To a'll'ufho'ml Iit may concern Be it known that I, JOHNl WILSON, ofthe city,

county, and State of New York, have invented a new and usefulImprovement in Horseclipping Machines;

and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled inthe art Ato makeand use the same, reference being had to the accompanying drawing fomifing part of this specification, in which- Figure 1 is a side view ot' myimproved horse-clipping machine. Figure 2 is a top view -ot` the same,partly in section, through the line ma', fig. l.

Figure 3 is a de tailvsectional viewof the same, taken through the li'ney y, fig. 2.

Figure 4 is a detail sectional view of the same, taken through the lines s, tig. 2.

Similar letters of reference indicate corresponding parts. l

'lhe purpose of my invention is to improve upon the machines heretoforeemployed by the public for clipping horses.

I will first describe my invention, and then clearly point it ont in theclaim.

.A is the foundation er base-plate of the machine,

the forward part or edge of which is made with a shoulder upon its upperside, and toit is-rlnlybut detachably secured by screws the lowercutter-plate l5.

In clipping-machines as heretofore constructed the lower cutter-platehas been formed as a solid part'ot' the main plate A; and as the tcct-hhave to be made very hard, and consequently are easily broken, theaccidental breakage of' one ol' the` teeth rendered the whole machineuseless.

By making the part of the plate upon which the teeth are formeddctachablc,'should one of the teeth he accidentally broken the plate llmay be easily detached, and replaced with a new plate at tritlingcxpense.

' and screws, are made ot' malleable cast-iron.

To the upper side of the shank oi the hase-plate A is secured, by ascrew or bolt, an arm, l), which curves upward and tbrwm'd, and in itsprojecting cnd is formed a bearing for the journal ofthe gearwheel E, towhich is attached a crank-hamlle, F, by means ot' which it. isoperated.A

Upon the projecting end ofthe arm D is also formed a bea-ring for theupper end of the short vertical shaft G, the lower end of which revolvesin a step or socket fornied for its reception in the rear part ot' thebaseplate A.

To the' lower part of the shaft 'G is attached a. small I gear-wheel, H,into which'the teeth ofthe gear-wheel ll mesh, so that thesaid shaft Gmay be revolved' by the revolution ot' the said gear-wheel E.

The gear-wheels E and H may, it' desired,- he' replacedl withfriction-wheels,

To the lower part ot' the shaft Gr, j ust .belowthe f gear-wheel H, is'attached, or upon it is forrn'ed',a'sinall eccentric, I, uponl which isplaced a ring, J, having lugs projectingl in opposite directionsfronr'its forward side, through holes, in which pass the fo rksformedupon the rear end of the lever K, so that the rear end ot' the saidlever maybe moved laterally or oscill'ate by the revolution of theeccentric I..

L is a projection, east solid upon the base-plate A, which passesthrough a: h ole formed' for its reception in the middle part of thelever K, the said lever resting upon a shoulder formed upon the basepart of said project-ion, as` shown in figs, 1 and 3.

'lhe forward end of the lever K is turned upward, and passes through aslot in the upper cutter-'plate M.`

The end parts of theslot in the plate M are enlarged, as shown in iig.2, so that, as the lever K is oscillated, only the side edges of itsturnedup forward end may hear against the plate M, giving it a'lateraloscillation.

The forward part ot' the fplate M is made flat, so

that its lower side mayrest squarely uponv the upper side ot' the lowerplate B, to which it is secured by screws- 0, the heads of which arecountersunk into the lower side ot' the lower cutter-plate 15.

'The screws O pass through holes in the lower eutter-plate 15, throughshort slots in the upper cutterplate lll, and serewinto screw-holes inthe bar P,

which extends across the upper sido ot the upper cntter-plate '3L llhehar or long washer l hassqnare projections formed upon its lower side,which enter the slots in the upper cutter-Nate M, and causethcsaidcutterplate to oscillatc in a straight line, and also give longerbearings tothe screws O, the said screws being thus nnatfected by theoscillation of the said cutter-plate, and not liable to be worked looseby the friction.

The rear part m ol' the upper cutter-plate M is curved upward, as shownin iigs. l and 2, to serve as a guai-dto prevent the hair from passingback and interfering with or clogging the operating mechanism.

The forward part ofthe'upper cutter-plate M is held down closely uponthe forward part of the lower cutter-plate l, to prevent the hair fromgetting between the twoplates, and thus' preventing the teeth from'operating properly, bythe spring plate Q, the forwardpart otl whichrests against the lower side of the rea'r parts of the said uppercutterplate M, as shown in tio'. l.

The middle part of the forward edge of the spring plate Q is cut away,as shown in dotted lines in iig. 2, so that it may not interfere withthe opera-tion ot' the leve) K.

The rear part of the spring plate has a hole formed through it, throughwhich passes the upper end ofthe projection L, the sides of .said upperend being eut away, as shoivn in iig. 2, to form shoulders for the saidplate to rest upon, so that Vit niay, not he moved by the loscillationof the lever K.

.The spring plate Q and lever K are kept in place upon the projectlon Lbythe screw R, which is screwed into a screw-hole formed in the `saidprojection, as

shown in gs. 1, 2, and 3.

lhe projection L thus servesas a pivot for the lever K to work upon,.andas a support for the spring plate Q; and its especial object `is toremedythe difficulty heretofore experienced with all similar machinesfrom the pivoting screw-holt 'or rivet Working loose with the friction,and the impossibility heretofore experienced of keeping it firmly inplace.

entirely removes this diiiculty, as the part of the plate A.

Having thus described iny invention,

pivot is a solid My construction' I claim as new and desire to secure byLetters Patent- 1. Air uppercutter-plate,M, provided with the np-ln'ardlymurved guard m', to prevent the niechanisx'n from being cloggedwith hair.

An improved ho1-se.-clipping machine, formed by the combination of thebase-plate A, handle O, arm

"1), crank gearfwheel E F or equivalent, shaft Gr, gearwheel H orequivalent, eccentric I, ring J, lever'K, solid projection L, lowerdctachz ble cutter-plate B, upper cutter-plate M having a gnard,m,formed upon its`"rear part, long washer and nut-bar P having squareprojections formed upon its lower side, screws O, and spring plate Q,with each other, substantially as herein shown and described, and forthe purpose set forth. f

The above specification oi' my invention signed by met-his 214th day ofMay, 1870. i
